Abstract: A lubricant holder for vertical conveying of lubricant using a crankshaft of a coolant compressor includes a sleeve element having a clear cross-section delimited by an inside wall, which cross-section extends along a longitudinal axis, from an upper end to a lower end, an inner element that has a mantle surface that extends along a longitudinal axis of the inner element, from a lower end to an upper end, wherein in an operating state the inner element is arranged within the clear cross-section with its mantle surface, at least in certain areas. At least one groove of the inside wall and/or of the mantle surface, which groove runs in spiral shape, has a varying angle of inclination, which preferably increases from the lower end to the upper end of the mantle surface.
